Communication Error
Communication with an application’s electronic control
unit has been unexpectedly lost. If reprogramming is not
in process, check the harness connections - disconnect
and reconnect the controller. If the problem persists,
consult the dealer for this controller. The controller can be
identified by the following manufacturer information:
NOTE: No weather values will be displayed or
documented until connection to the Application
Controller is restored.
Sensor Orientation Incorrect
The plastic nut assembly on the sensor is hand tightened
and may loosen over time. Periodically check that the
captive nut is still tight and alignment of the sensor is
correct.
If the plastic nut assembly is tightened with a tool, instead
of hand tightened, it may break or crack. Hand tighten
only. A damaged nut assembly may affect the orientation
of the sensor from facing the front of the machine. If any
part of the plastic nut assembly is cracked or broken,
replace plastic nut assembly.
The steel extension tube that the sensor is mounted
on may loosen over time. A loose extension tube may
affect the orientation of the sensor. Periodically check
that connection between the extension tube and ratchet
assembly are still tight.

Degraded Weather Measurements
Do not expose the sensor to temperatures greater than
65° C (149° F). If sensor has been exposed to temperature
greater than 65° C (149° F) calibration of the sensor may
no longer be accurate.
